Specification of Letters Patent.

Patented July 7, 1914..

To all whom it may concern:

Be it known that I, EDWIN O. LAWRENCE, a citizen of the United States,residing at Port Jefferson Station, in the county of Suffolk, State ofNew York, have invented certain new and useful Improvements inCesspools; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same. i

This invention relates to cess pools and has for an object to provide anoverflow pipe which prevents flooding of the cess pool by drawingifromthe center of the cess 001. p A further object is to provide an overflowpipe which will not get clogged, and which will further be ventedtoprovidefor the escape of odors through the'vent pipe from the'house sinkor otherwise. I

A still further object is to provide an extremely simple device of thischaracter which may be constructed at. a minimum cost and'which will noteasily get out of.

tion consists of certain novel details of construct-ion and combinationof parts herein after fully described and claimed, it being understoodthat various modifications may be made in the minor details ofconstruction within the scope of the appended claim.

In the accompanying drawing illustrating this invention :Figure 1 is aside elevation of my improved cess pool. Fig. 2 is a longitudinalsectional View through the parts shown in Fig. 1. Fig. 3 is a plan view.Fig. 4 is a detail perspective View of the draw oil or overflow pipe.

Referring now to the drawing in which like characters of referencedesignate similar parts, 10 designates a cylindrical cess pool which maybe formed of brick or otherwise and is of ordinary construction and hasan intake pipe through the uppermost portion of its top as illustrated.

In carrying out my invention I insert a straight pipe 11 through thebottom of the cess pool, the pipe extending considerably below thebottom and being equipped with a pointed ground penetrating extremity 12sink, there being a T-coupling 141 inserted in the pipe above thehighest level which the water in the cess pool may reach, the lateralbranch of the T-coupling facilitating the odors and foul gases from thecess pool, entering the pipeand being led off through the vent pipeofthe sink. There is a second T-coupling 15 inserted in the pipe at orjust below the highest water level in-the cess pool, the lateral branchof this coupling being connected with the lateral branch of a secondT-coupling 16, one of the alined branches of the latter being closed bya plug 17, and the other being connected to a depending pipe 18 which isdisposed parallel with the pipe 11 and extends to about the center ofthe cess pool, this pipe 18 being open at the bottom.

In operation, when the cess pool becomes filled to overflowing, thewater will escape through the pipe 18, T-couplings 1 6 and 15 and downthrough the pipe 11 into the sand.

The cess pool is always full and the grease floating on top gives themicrobes a chance to do away with the'solids at the bottom of the cesspool, therefore the cess pool never 1 becomes full of solids up to thepipe 18.

. What is claimed, is

The combination .with a cess pool for sewerage of an outlet pipeextending vertically through the cess pool and terminating at the lowerend below the cess pool and being there provided with outlet openings,

an intake pipe adapted to be submerged in the contents of the cess pooland having a horizontal pipe connection at the upper end with saidoutlet pipe, the intake end of said intake pipe being disposed at aboutthe center of said cess pool and said horizontal pipe connection atabout the normal high water level of said cess pool whereby liquidenters said intake pipe from the center of the cess pool and escapesthrough said pipe connection into said outlet pipe, the solid matteraccumulatin in the bottom of said cess pool below said intake pipe whilethe stroying said solid contents whereby said and a vent pipe connectedto said outlet/pipe liquid level of said cess pool;
